Antirrhinum plant named ‘Pmoore07’

ABSTRACT

A new cultivar of  Antirrhinum , ‘Pmoore07’, that is characterized by its compact, upright plant habit, its extended bloom season, its narrow, elongated flowers that are purple-pink in color with a whitish yellow throat, and its increased resistant to fungal diseases, especially,  Puccinia antirrhini  (leaf rust) as compared to other  Antirrhinum  cultivars.

Botanical classification: Antirrhinum majus.

Cultivar designation: ‘Pmoore07’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Antirrhinum majus and will be referred to hereafter by its cultivar name, ‘Pmoore07’. ‘Pmoore07’ represents a new snapdragon, a half-hardy herbaceous perennial typically grown as an annual.

The new cultivar was derived from a controlled breeding program by the Inventor in Longstock, England. The objective of the breeding program is to develop new cultivars of Antirrhinum that are more disease resistant and produce unique plant forms and flower colors. The Inventor made a cross in July of 2010 between Antirrhinum majus ‘Eve Grey’ (not patented) as the female parent and an unnamed proprietary plant of Antirrhinum majus subsp. tortuosum from the Inventor's breeding program as the male parent. The Inventor selected ‘Pmoore07’ in August of 2011 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by the Inventor via softwood stem cuttings in October of 2011 in Longstock, England. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Pmoore07’ as a unique cultivar of Antirrhinum.

-   -   1. ‘Pmoore07’ exhibits a compact, upright plant habit.     -   2. ‘Pmoore07’ exhibits an extended bloom season, flowering from         early July until first frost, with deadheading, in England.     -   3. ‘Pmoore07’ exhibits narrow, elongated flowers that are         purple-pink in color with a whitish yellow throat         (Penstemon-like).     -   4. ‘Pmoore07’ exhibits increased resistant to fungal diseases,         especially, Puccinia antirrhini (leaf rust) as compared to other         Antirrhinum cultivars.

The female parent of ‘Pmoore07’, ‘Eve Grey’, differs from ‘Pmoore07’ in having flowers that are less pink in color, in being more susceptible to fungal diseases, and in having a flowering period that is shorting in length. The male parent of ‘Pmoore07’ differs from ‘Pmoore07’ in having a more open plant habit and in having differently shaped flowers. ‘Pmoore07’ can be most closely compared to the Antirrhinum cultivars ‘Liberty Pink’ (not patented) and ‘Rocket Pink’ (not patented). ‘Liberty Pink’ differs from ‘Pmoore07’ in being larger in overall size, in having an earlier commencing bloom season, and in having flowers that are light pink in color. ‘Rocket Pink’ differs from ‘Pmoore07’ in being smaller in overall size, in having a spreading plant habit, and in having flowers that are deep pink in color.
